Thick wall Inconel 718SPF polished pipe

Overview

As a leading supplier & manufacturer in China, GNEE group supply cost-effective Inconel 718SPF Products.

INCONEL alloy 718SPF is a specifically "tailored" version of INCONEL alloy 718, designed for the superplastic forming process. The alloy is optimized for the process by rigorous control of composition, melt practice and rolling conditions.

INCONEL alloy 718SPF was developed to meet the need for a nickel-base alloy suitable for manufacture into complex shaped components subject to a combination of high temperature, high temperature corrosion and high stress. INCONEL alloy 718SPF meets all the mechanical property requirements of AMS 5596G, as annealed plus aged, as well as all requirements of AMS 5950, which is specific to INCONEL alloy 718SPF.

Superplastic forming, now highly sophisticated and used extensively for producing commercial and military aircraft components, is an ideal process for manufacturing complex shaped parts. Use of superplastic forming can enhance component performance and reliability while lowering overall manufacturing cost by reducing the need for extensive welding or other joining methods, lowering the inventory of parts and simplifying the manufacturing process.

Mechanical Properties
INCONEL alloy 718SPF is produced with an annealed temper. The alloy is produced to a grain size of ASTM No. 10 (0.01 mm/0.0004 in) or finer. As produced, INCONEL alloy 718SPF sheet meets the strength and ductility requirements of AMS 5596G, as annealed plus aged.

Corrosion Resistance
INCONEL alloy 718SPF, like alloy 718, has excellent resistance to corrosion in many media. This characteristic, similar to that of other nickel-chromium alloys, is a function of its composition.

Nickel contributes to a resistance to corrosion by many inorganic and organic compounds, other than those that are strongly oxidizing, throughout wide ranges of acidity and alkalinity. It is also useful in providing resistance to chloride- ion stress-corrosion cracking. Chromium imparts an ability to withstand attack by oxidizing media and sulfur compounds. Molybdenum is know to contribute to resistance to pitting in many media.

Above all, INCONEL alloy 718SPF is important for its strength and corrosion resistance at high operating temperatures.
